Patent DE-2107350-A1 (DE)
Title: Multi-layered suspension/emulsion copoly-mer particles
IPC: C08F285/00
Filed: 1971-02-16
Abstract: Cheap and easily produced particles to improve the impact strength of hard and brittle polymers without affecting their other desirable physical properties are obtained by emulsion-polymerisation of vinyl chloride (or styrene or other vinyl compds.) to form the nucleus of the particle, with a size of 0.3 mu (or slightly larger, vitrification temp. >25 degrees C), forming a layer of a rubber-like emulsion polymer (pref. polybutylacrylate with a little methacrylic acid, vitrification temp. 25 degrees C) to a size of about 1 mu and finally forming a layer of a suspension polymer (pref. PVC) onto the rubber (it may be intimately mixed with the rubber). The particles formed are dried and form a free-flowing powder, which is mixed into the hard polymer (usually PVC) by usual methods prior to working.

Title: Fish location - for beheading using photo-electric cell to determine tail position as reference point for cutting blade
Inventor: DUTKIEWICZ D
IPC: A22C25/14
Filed: 1971-07-12
Abstract: Based on the principles of fish proportions, a photoelectric detection system is used to locate the position of the tail in the cutting trough, and this position gives an accurate location for the cutting blade to remove the fish head without wastage. The movement of the photoelectric cell to determine the tail position is translated into a mechanical movement either to the trough or the cutting blade, to give an accurate relative positioning between fish and blade, to ensure the head is removed at the gills, without wastage.

Title: Pressure die casting machine - with easy press height changing
Inventor: KLENK WALTER
IPC: B22D17/32
Filed: 1972-04-29
Abstract: The piston has a reduced dia. at each end to form two separate annuli with the cylinder walls, and is bored right through and has a tube inserted to form a further annulus. These are interconnected by a pipe so that, with a control valve in one position, the admission of fluid to the cylinder moves the press head up w.r.t. the cylinder housing, allowing a different sized distance piece to be put in. With the valve in the alternative position, press. is equalised at either end of the piston so that the press sinks on to the distance piece where it can be locked in position by any suitable means.

Title: Spot welding gun pressure intensifier - with twin piston air cylinder for approach- welding stroke
Inventor: ZIMMER ERNST
IPC: B23K11/31
Filed: 1973-06-05
Abstract: A pressure intensifier for spot welding guns includes a compressed air cylinder which can be moved relative to a second stationary piston. Its first piston is coupled by a piston rod, with collars between which a hollow piston can move against springs. The hollow piston is guided in sealed bores which divide the hydraulic cylinder in three parts. The two outer parts communicate with the two ends of the welding cylinder. This eliminates any spring in the welding cylinder for the approach stroke and saves time. Any hydraulic fluid leakage can be made up without risking any vacuum in the system.

Title: Automatic volume control for car radio - matches its output volume to surrounding noise by use of noise transducer
IPC: H03G3/32
Filed: 1974-03-22
Abstract: The automatic noise matching of a car radio loudspeaker etc. is carried out by using a separate microphone for receiving the ambient noise. The microphone converts the noise energy and applies it to the loudspeaker control unit. The microphone has a directional characteristic, and its frequency range is limited by a bandpass filter to a bandwidth of 50-500 Hz. The useful sound to noise ratio is determined by a control unit between the microphone and loudspeaker. Between both electroacoustic transducers, i.e. the microphone and the loudspeaker may be inserted and adjuster of the rated value which can be logarithmically set to match the human perception.

Patent DE-2438386-A1 (DE)
Title: Coupling for ejector of injection mould - provides axial and radial play between ejector pin and plate
Inventor: MUELLER HANS
IPC: B29C45/17
Filed: 1974-08-07
Abstract: A coupling for joining together the ejector pin and ejector plate of an injection moulding machine is constructed as follows: the pin has a smooth forward end with a tapering conical or chamfered portion to provide a lead-in; this smooth, cylindrical front end is followed by a relatively short threaded region, axially shorter than the cylindrical region but of larger core diameter; attached to the ejector plate is a coupling half which engages, with some radial and some axial play, a second coupling half, into which the threaded portion of the pin can engage. This results in some axial and radial play between the ejector pin and ejector plate. The max. possible axial relative movement between the two coupling parts exceeds the axial length of the threaded portion of the pin, so that when the pin and ejector plate move together, the threaded portion of the pin engages the threaded portion of the second coupling part and moves it axially with it. Thus the pin and the ejector plate can follow exactly guided paths with slight play between them, preventing any possibility of jamming. At the same time, the total coupling volume is small.
